Abstract
In this paper, through the mechanical property test of lightweight ceramsite concrete partition board, the bending bearing capacity of different thickness of the board is measured. Through the test, the influence of humidity on the ceramsite concrete wall panel and the vertical compressive performance of the ceramsite concrete slab are studied, and the vertical compressive bearing capacity is obtained. The results show that: the bearing capacity of different thickness wallboards used in the test is far greater than 1.5 times of the dead weight of the plates. Through the failure load of the plates, the deflection values and bending stiffness values of the wallboards in the actual engineering are obtained. The vertical allowable loads of the three thickness plates are 129.73KN, 311.90KN and 127.02KN.
Highlights
The flexural performance of wallboard is a very important and fundamental factor
Zhou Xuejun et al [5] carried out the flexural bearing capacity test of autoclavated concrete wall panel with autoclavated porcelain powder to study the mechanical properties of the wall panel
Chen Bo[8] carried out flexural bearing capacity test and axial compression test on assembled light steel composite insulation exterior wall panel
Summary
The flexural performance of wallboard is a very important and fundamental factor. It is used as the external wall to bear a certain wind load, and used as the internal wall to bear a certain furniture load, etc., the flexural performance directly affects its application in engineering. The air humidity is an inevitable influence factor on the bending performance of wall panels. Zhou Xuejun et al [5] carried out the flexural bearing capacity test of autoclavated concrete wall panel with autoclavated porcelain powder to study the mechanical properties of the wall panel. Wang Yue [7] carried out flexure bearing capacity test on autoclaved porcelain powder aerated concrete wallboard, and analyzed its deformation capacity and fracture development mode. Chen Bo[8] carried out flexural bearing capacity test and axial compression test on assembled light steel composite insulation exterior wall panel. The influence of air humidity on the actual flexural bearing capacity of lightweight ceramsite concrete partition board is analyzed. The slab is cut into prism and tested under axial compression, the vertical allowable load of the slab is obtained by analyzing the data, which provides some theoretical basis for its application in practical engineering
